Hydraulic Roller Lifters - BBC

Crower hydraulic roller lifters for BBC (big-block Chevrolet) engines are designed for serious engine builders who demand precision valve actuation. These lifters are suitable for a variety of applications, including carbureted street engines, naturally aspirated performance machines, and boosted setups. They are a direct replacement for worn flat-tappet lifters, enhancing valve control and performance.

Engineered for high-RPM stability and quiet operation, these hydraulic roller lifters feature a roller design that rides on a precision-ground cam lobe, reducing friction and allowing for tighter valve timing events. The integral oil gallery system automatically adjusts preload, maintaining consistent lash across various engine speeds and temperatures. The hardened roller wheel and precision-honed bore are designed to prevent scuffing and wear, ensuring long-lasting performance.

These lifters are compatible with factory and aftermarket BBC cylinder heads, making them an excellent choice for both restoration projects and performance upgrades. This 16-lifter set is suitable for BBC engines ranging from 396 to 502 cubic inches, including Chevrolet Performance crate engines. Installation requires a compatible BBC camshaft designed for hydraulic roller lifters.
